How we handle external mastic in Trolliloes
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you have brick movement joints where the sealant has split and weathered mastic that no longer stretches, we can help, whatever the surface.
In a village or hamlet like Trolliloes, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Your job is guaranteed for a year, as with all our work.

The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from a few hours to several days, depending on the building. Somewhere as small as Trolliloes, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us about any water getting in
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

Related advice
Landlord and commercial work in Trolliloes
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before the bead.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Signs you need external mastic in Trolliloes
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Look out for any of the following:
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Joints where the bead has come unstuck
- Plants rooting in failed movement joints
In and around Trolliloes, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What external mastic looks like in Trolliloes
Historic houses like Horselunges Manor (about 3.7 miles south-west) are a reminder that the area around Trolliloes has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

How to look after the new joints
After the cure time, these simple habits help:
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Keep soil, plants and ivy away from the joints
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
